Operation terminal, voice inputting method, and computer-readable recording medium

摘要

An operation terminal includes: an imaging part configured to image a space; a human detecting part configured to detect a user based on information on the space imaged; a voice inputting part configured to receive inputting of the spoken voice of the user; a coordinates detecting part configured to detect a first coordinate of a predetermined first part of an upper limb of the user and a second coordinate of a predetermined second part of an upper half body excluding the upper limb of the user based on information acquired by a predetermined unit when the user is detected by the human detecting part; and a condition determining part configured to compare a positional relationship between the first coordinate and the second coordinate, and configured to bring the voice inputting part into a voice inputting receivable state when the positional relationship satisfies a predetermined first condition at least one time.
